How does a camera work?

[@moebro38]

Your visuals are amazing. I usually have trouble learning technical stuff like this, but as a visual learner, this has done way more for me than any lecture could! I wasn't expecting a huge amount of thorough explanation and I appreciate how in depth this video is. Nothing is better than being able to visually comprehend this!

10 out of 10. Man ,,,,the way it is linked with evolution that was amazing

[@YogeshPersonalChannel]

Exactly. I was going to say the same. The last few minutes were fabulous. We always read about the em spectrum and the visible region of it shown in color. Well color is just in mind. Other species might have their different 'color' region sliced from em spectrum

[@Vysair]

@@YogeshPersonalChannel Mantis shrimp can see the most 'light' wave

[@pratulvenkatesh]

12:15 While I agree the spectrum of colors we see is partially influenced by the light emitted by our star, visible light isn't "visible" because it's the only thing available. Rather visible light is the em wave of the right wavelength capable of interacting with most of the matter at the molecular scale. For e.g we cant see something by bouncing radiowaves off of it as it just passes through unless it is a few metres thick. Quite a beautiful coincidence don't you think how most of the light we receive from our star happens to be in the visible spectrum.

[@pratulvenkatesh]

I happen to watch this documentary recently on how animals see and it's honestly so fascinating. Houseflies have 4 types of color receptors 2 of which like in the UV range :o Did you know mantis shrimp have SIXTEEN types of photoreceptors! That way they don't have to calculate what color they are looking at and can detect the color directly. They can even detect other characteristics of light and apply them such as polarization. You'd think it'd be only to detect the environment better but they use this varying polarized light to send different signals It's so amazing how the colors we see is an incredibly human only perception, other creatures may be seeing the same light but can perceive completely different color

[@shivamverma9515]

Read everything but understood nothing 😅

[@pratulvenkatesh]

@@shivamverma9515 Hey! So essentially, the range of the electromagnetic spectrum that we term as 'visible light,' is visible only because it has the right wavelength to interact with most matter. By interact, I am referring to reflection, absorption, etc. In comparison if the light ray is of too high wavelength (or too less), such as radiowaves and X-rays respectively, then these kinds of rays just pass through most matter. Visible light (red-blue part of spectrum) is 'visible' because it's the right size to interact and light up most things. It just happened to be a coincidence that the majority of the light we receive on earth is in this spectrum! Hope that, that explained it better?

[@scubasteve6175]

are there stars that don't emit visible light or mostly produce wavelengths outside of our spectrum? i'm just curious as you seem very knowledgeable

[@pratulvenkatesh]

@@scubasteve6175 yup the hotter the star is, shorter the wavelength of light emitted by stars is (more energy) so there are high energy stars that produce x-rays and gamma rays produced by neutron stars, pulsars, supernovae explosions, etc. on the lower end there are cold stars that produce faint infrared rays such as brown dwarfs which are difficult to observe with visible light telescopes as they don’t produce much visible light and only infrared.

Our smart phones are pretty thin. I am impressed that within that thin space there’s a tiny motor which moves the lenses back and forth for focusing. And there are semiconductor layers and micro lenses for each pixel points. There are sixteen million of them in a moderate quality camera. This degree of miniaturisation is inconceivable for a lay person like me. I prostrate before the collective genius of the scientists, designers and engineers who made the smart phone cameras work so well. I don’t even want to ask who makes the camera lenses, micro lenses, what is the manufacturing method. It must have been a huge effort to squeeze in all these intricate details in a fourteen minutes video. I felt that this episode could have been restricted to mere description of the smartphone cameras and the electronics could have been discussed in a separate video.

[@HyungnamGu]

To capture color images, a filter has to be placed over each cavity that permits only particular colors of light. Virtually all current digital cameras can only capture one of three primary colors in each cavity, and so they discard roughly 2/3 of the incoming light. As a result, the camera has to approximate the other two primary colors in order to have full color at every pixel. The most common type of color filter array is called a "Bayer array" A Bayer array consists of alternating rows of red-green and green-blue filters. Notice how the Bayer array contains twice as many green as red or blue sensors. Each primary color does not receive an equal fraction of the total area because the human eye is more sensitive to green light than both red and blue light. Redundancy with green pixels produces an image which appears less noisy and has finer detail than could be accomplished if each color were treated equally. This also explains why noise in the green channel is much less than for the other two primary colors.

1. I think it is because of the range of frequency that green covers and 2. Depending on the star it may be difficult for us to see in our current state. ALSO cameras can pick up ultraviolet light that our eyes cannot. You can test this yourself by pushing the buttons on a remote aimed at a camera.

[@BranchEducation]

@@alakanandamishra2375 That's definitely a very possible case, however the camera is closer to 1/10th the cost of the phone. Maybe some phones have the camera as 1/4 the bill of materials cost. technology.ihs.com/api/binary/596801 shows the cost breakdown of the Iphone X, with the dual camera at $35, and the whole phone parts cost at $370. Maybe the lack of high-quality camera is related to the fact that Iphone/Samsung gets significantly better costs on buying massive quantities of cameras, and thus for an individual laptop the cost is a lot higher for a camera?
